7 Claims.

This invention relates to wrapper applying mechanisms for cigar machines, more especially to improvements in the construction of the tuck needle which holds the entering end of the cigar wrapper against the tuck end of thecigar bunch during the first part of the wrapping process.

The main object of this invention is to provide for easily removing or conveniently replacing the tuck needle, particularly topermit removal thereof forwardly through the needle guide bushing. Heretofore, when it was desired to remove the needle, it was done by detaching the link whereon the needle was mounted from the cam-actuated lever carrying the link and removing the latter rearwardly. machines, there is no space for removal of the needle rearwardly, wherefore it is an object of the invention to permit removal of the needle forwardly if desired. However, in one embodiment of the invention illustrated herein the needle may be removed without detaching its supporting link, rearwardly through its mount.

A further object is to provide an improved mount for the needle having a ball-and-socket construction whereby it is supported from a link connecting it to the cam lever to permit swiveling of the needle while pressing the entering end of the wrapper against the bunch.

Still another object is to provide in an improved construction of the needle a reduced portion providing a locating surface or shoulder engaging the mount to position the needle in its operative position.

With these and other objects not specifically mentioned in view, the invention consists in certain combinations and constructions which will be hereinafter fully described, and then specifically set forth in the claims hereunto appended. In the accompanying drawings which form a part of this specification, and in which like charactors of reference indicate the same or like parts:

Fig. l is a plan view of the tuck needle and partial view of the cigar wrapping mechanism;

Fig. 2 is a side elevation of the same, partly in section;

Fig. 3 is a sectional end elevation of the tuck needle supporting lug illustrating the ball-andsocket joint and securement for the tuck needle, taken on line 3-3 of Fig. 2;

Fig. 4 is a similar view of the tuck needle supporting lug showing the cotter in a position releasing the .tuck needle;

Fig. 5 is a side elevation of a modified form of the tuck needle support;

In recent types of cigar wrapping Fig. 6 is a plan View of the same; and

Fig. '7 is an end elevation of said modified form of tuck needle supporting lug, taken on line l-'| of Fig. 6.

Referring to Figs. 1 and 2, the tuck needle I0 is shown in connection with a cigar wrapping device such as disclosed in the co-pending application, Serial No. 107,792, of October 27, 1936, by James P. Durning. In said wrapping device the cigar bunch is placed, as is customary, between a number of rollers I I rotated in unison by suitable gears !2. Furthermore a suitable mechanism (not shown) is employed to open and close said rollers to admit said bunch and permit the cigar C to be taken away after the completion of the wrapping process.

The entering end of the wrapper is stripped from a suitable wrapper carrier (not shown) by means of the tuck needle H) which holds the stripped end of said wrapper tight against the tuck end of said cigar bunch, during approximately 1 A; revolutions thereof, while the latter is rotated by said rollers I I, so that the wrapper, assisted by the well known action of a tension plate I3, is rolled in spiral form tightly about the bunch.

The tuck needle Ill is supported by means of 2, lug l4 (Figs. 1, 2, 3, and 4) and projects into the wrapping device through a guide bushing l5 held by the wrapping device frame 16. At its shank the tuck needle is provided with an annular groove i! (Figs. 3 and 4) which engages with one leg E8 of a cotter pin IS. The other leg 20 of said cotter I9 is loosely supported Within a hole 2! of lug I4. In normal or working position cotter i9 will hold needle It firmly to lug M (Fig. 3). In case it is desirable to remove or replace said needle, clip 19 is pulled in the direction indicated by an arrow in Fig. 3, causing the bent end 22 of clip leg Hi to ride on the bottom 23 of a slot 24 of lug i4, thus raising said leg i8 and disengaging the latter from the annular groove ll of needle I0 and freeing the same for removal.

The needle Ill is actuated by means of a cam operated lever 25 (Figs. 1 and 2) connected to lug M by a link 26. The latter is pivoted to lug M by means of a ballpin 21 which is loosely held in said lug by a suitable screw 28. During operation the rear end of needle Ii] is guided by a slotted plate 29 of well known construction. Said plate 29 is held by a bracket 36 attached to the wrapping device frame IS.

A modification of this invention is shown in Figs. 5, 6, and 7 wherein a needle supporting lug 14a is split longitudinally at 3| and equipped with a clamping screw 32 which, when tightened, will hold said tuck needle. Removing or replacing of the latter is easily achieved by simply loosening said clamp screw 32. In this modification the needle I is taken out of lug Na in a forward direction through the guide bushing. The shank of said needle being provided with a shoulder [0a, can be put back in the same position without difiiculties, shoulder Illa stopping against the front end of lug I la. In order to assure a swivel motion of lug Ma, the latter, in this modification is pivoted to link 26a by means of a barrel shaped pin 33. The tuck needle and lug, of course, are actuated in the same manner .by the cam operated lever 25.

What is claimed is:

1. In a cigar machine having a needle guide bushing, the combination with a mount, of a tuck needle projecting through said bushing and releasably secured in said mount and adapted to be withdrawn forwardly through said bushing when released, said mount being split, and provided with a longitudinal bore, and said needle being provided with a locating abutment on its shank engaging said mount, and said mount being equipped with a clamp screw for holding it on the needle shank.

2. In a cigar machine having a needle guide bushing, the combination with a tuck needle projecting through said bushing, of a ball-andsocket joint whereon said needle is fastened, and means supporting said joint and operating to intermittently move the needle through said bushing into operative position.

3. In a cigar machine having a needle guide bushing, the combination with a single unitary mount, of a tuck needle releasably secured in said mount in immovable relation thereto and having a shank provided with an integral abutment engaging said mount for locating said needle in a predetermined position and adapted to be withdrawn forwardly through said guide bushing when released.

4. In a cigar machine having a needle guide bushing, the combination with a mount, of a tuck needle releasably secured in said mount in immovable relation thereto and adapted to be withdrawn forwardly through said needle guide bushing when released and having a reduced portion providing a shoulder abutting the end of said mount adjacent said needle guide bushing to locate the needle relative to said mount, said mount having a configuration adapted to enter and engage said bushing to locate the needle in a predetermined operative position.

5. In a cigar machine, the combination with an actuating member, of a single unitary mount pivotally supported on said member, a tuck needle supported in said mount, and means for releasably securing the needle in axially immovable relation in said mount, said needle being adapted to be withdrawn axially from said mount when released.

6. In a cigar machine having a needle guide bushing, the combination with a mount, of an actuating member whereon said mount is swiveled, said member being movable to advance said mount into said bushing to project the needle through said bushing into operative position, a tuck needle projecting through said bushing and releasably secured in said mount in axially immovable relation thereto and adapted to be withdrawn axially and forwardly through said bushing when released, said needle having an annular groove in its shank, and said mount being provided with a longitudinal bore wherein the shank of said needle is seated, a slot communicating with said annular groove, and a cotter projecting through said slot into said groove.

7. In a cigar machine having a needle guide bushing, the combination with an actuating member, of a single unitary mount pivotally supported on said member, a tuck needle supported in said mount, and means for releasably securing said needle in axially immovable relation in said mount, said needle having a size and shape permitting it to be withdrawn axially and forwardly through said bushing when released.
